Abstract

To develop an alternative material to Cu-Be alloys, Cu 93.5Zr5.5Ag1 non-equilibrium alloy sheets were prepared through the simple production process of die-casting, annealing and cold rolling. The developed sheets exhibit ultrahigh tensile strength of 1530 MPa, plastic elongation of 1.2% and good electrical conductivity. These results suggest that the developed sheets have excellent properties and constitute an alternative material to Cu-Be alloys.
